A lay of the Elder Days, that told the story of Eärendil's voyages in his ship Vingilot. Beginning with the building of the ship, it tells of his adventures sailing the Great Sea in search of the Valar. Those early voyages ended in failure, but he had many strange encounters among the Enchanted Isles. At last he abandoned his search and turned homeward, but as he approached the shores of Middle-earth, a white bird descended from the sky onto his deck. This was his wife Elwing, rescued by Ulmo from the attacking Sons of Fëanor, and she brought with her a Silmaril.

After that time, Eärendil and Elwing remained in the West, so the story of the lay could not have come directly from them. With Eärendil through all his adventures, though, were three mariners: Aerandir, Erellont and Falathar. These three were all returned to Middle-earth by the Valar, and so the lay would seem to be based on their accounts of their journeys with Eärendil.
